Materials Engineer

Materials engineers develop, process, and test materials used to create a range of products, from computer chips and aircraft wings to golf clubs and snow skis. They work with metals, ceramics, plastics, composites, and other substances to create new materials that meet certain mechanical, electrical, and chemical requirements.

Materials engineers typically do the following:
  • Plan and evaluate new projects, consulting with others as necessary
  • Prepare proposals and budgets, analyze labor costs, write reports, and perform other managerial tasks
  • Supervise the work of technologists, technicians, and other engineers and scientists
  • Design and direct the testing of processing procedures
  • Monitor how materials perform and evaluate how they deteriorate
  • Determine causes of product failure and develop solutions
  • Evaluate technical specifications and economic factors relating to the design objectives of processes or products

Materials engineers create and study materials at an atomic level. They use computers to replicate the characteristics of materials and their components. They solve problems in a number of engineering fields, such as mechanical, chemical, electrical, civil, nuclear, and aerospace.

Materials engineers may specialize in understanding specific types of materials. The following are examples of types of materials engineers:

Ceramic engineers develop ceramic materials and the processes for making them into useful products, from high-temperature rocket nozzles to glass for LCD flat-panel displays.


Composites engineers work in developing materials with special, engineered properties for applications in aircraft, automobiles, and related products.


Metallurgical engineers specialize in metals, such as steel and aluminum, usually in alloyed form with additions of other elements to provide specific properties.


Plastics engineers work in developing and testing new plastics, known as polymers, for new applications.


Semiconductor processing engineers apply materials science and engineering principles to develop new microelectronic materials for computing, sensing, and related applications.
个性与兴趣
Materials engineers typically have an interest in the Doer, Thinker and Persuader interest areas, according to the Holland Code framework. The Doer interest area indicates a focus on working with tools and machines, and making or fixing practical things. The Thinker interest area indicates a focus on researching, investigating, and increasing the understanding of natural laws. The Persuader interest area indicates a focus on influencing, motivating, and selling to other people.

If you are not sure whether you have a Doer or Thinker or Persuader interest which might fit with a career as a materials engineer, you can take a career test to measure your interests.

Materials engineers should also possess the following specific qualities:

Analytical skills. Materials engineers often work on projects related to other fields of engineering. They must be able to determine how materials will be used in a wide variety of conditions and how the materials must be structured to withstand the requirements of those conditions.


Math skills. Materials engineers use the principals of calculus and other advanced topics in math for analysis, design, and troubleshooting in their work.


Problem-solving skills. Materials engineers must understand the relationship between the structure of materials and their properties and means of processing, and how these factors affect the product. They must also figure out why a product might have failed, design a solution, and then conduct tests to make sure the product does not fail again. This involves being able to identify root causes when many factors could be at fault.


Speaking skills. In supervising technicians, technologists, and other engineers, materials engineers must be able to state concepts and directions clearly. When speaking with managers at high-level meetings, these engineers must also be able to communicate engineering concepts to people who do not have an engineering background.


Writing skills. Materials engineers must write plans and reports clearly so that people without a materials engineering background can understand the concepts.
